TRatioPlot question

Hi All,

I created a TRatioPlot using two histograms, a reconstructed IM_PipPim distribution and a generated IM_PipPim distribution. I understand the lower plot that is produced is a TGraphAsymmErrors.

My question is, if I have to divide real data in the form of a TGraph, how can I use the acceptance plot (lower plot produced from TRatioPlot above) to do this? Is there anyway to extract each point and its error from the lower plot of the TRatioPlot?
